Stuma the okapi at Chester Zoo, 30 December 2009

I'm not sure ... there was an okapi outdoors in the enclosure closest to the red river hogs, and after I had looked at the giraffes indoors, I saw this okapi indoors. When I went back outside, there was no sign of an okapi outdoors, so I don't know if I saw the same okapi outside and then inside, or whether I saw both of them

EDIT: I'm attaching the photo from outdoors, so that you can perhaps confirm the identity of the okapi. Looking at the leg patterns, I now think that I have seen both of them.
